My Grant combi oil boiler is giving me quite a headache at the moment. When I returned home last Friday I'd no heating or hot water. An engineer called the next day and diagnosed a faulty pressure switch. This was changed and everything seemed ok. However then the boiler began to lose pressure...
Hi all,
I'm trying to source a replacement pump for my heating system, I suspect the current pump is an older version that has been superseded, could anyone advise what the latest model would be or an equivelant?

Any help would be greatly appreciated :)

Our boiler is in the loft and I encountered a leak in a roof above our side extension store room which has transpired to be from the boiler condensate pipe. It was cracked at an elbow so the plumber we use has replaced this and hopefully all will be well with that joint.
This later prompted me...
Is the minimum output of this boiler 8.1kw, (max output 24.0kw), I don't see anything in the MIs re this, one would expect a turndown ratio of more than 3:1, surely?
Also what is the relationship of Bosch and Wocester Bosch?, they only mention Bosch in the manual.
My Vaillant boiler now only fires up for around 30 secs then goes off. The egg timer symbol then appears and flashes for several minutes. After that it fires up again and heats the rads. Would be grateful if anyone could suggest why this is happening. Thanks.

When I set it to be on via phone, light A comes on (telling it to be on), but light B won’t come on, so the boiler doesn’t start. I either need to set A on and off several times via phone, or turn it off and on again via switch (C).
When I set the water to be on, it works instead, and green...
Hi all
Wondering if you could help with this strange issue.
I have a Vaillant ecotec 637 (set to 20kw part load) which was connected via a LLH to my system of 3 zones; DHW and 2 radiator zones. The gas usage was high and didn’t feel the boiler was modulating, so yesterday I decided to remove...

I reckon if I did a survey of 100 heating engineers, asking what would they recommend for heating a granny annexe being built onto the side of my house, in place of the garage, most would give me a suggestion to put in a) an extension to the existing boiler rad circuit & electric water heaters...

I've extended an existing 'run' of radiators - the last one on the run ( in downstairs kitchen) is cold.
The first rad added is...
Some advice needed please re a 3 year old combi gas boiler. The hot water works but no heating. A gas engineer was already booked to do the annual safety check before the fault developed. He said the boiler is ok with no fault. He said there must be a leak under the floor boards causing hot...

Wb 4000 recently installed, and just balanced the rads with around 16 degree delta across most rads.
I'm trying to make sure that the return temperature to the boiler are less than 55 degrees to ensure condensing is occurring.
